Chinese Journal of Clinical Psychology 2000;0(04):-
Earthquakes affect numerous people,among whom many may develop PTSD.Therefore,easily disseminated and effective psychological interventions are urgently needed.The clinical practice guidelines developed by the International Society for Traumatic Stress Studies suggested that exposure therapy was the most empirically supported treatment for PTSD.The present study introduced Behavioral models of Posttraumatic Stress Disorder,major process of Exposure treatment for PTSD and relative problems.Compared with other treatments for PTSD,the theory models and techniques of Exposure treatment of PTSD are easier and readily lend themselves to dissemination.Considering serious situation now and in the future after this earthquake in Sichuan,clinical professionals should pay attention to exposure treatment of PTSD.
2.Patterns of Attentional Bias of Highly Anxious Individuals by Repeating the Occasions of Word Stimulus
Chinese Mental Health Journal 2002;0(11):-
Objective:This study aimed to investigate the pattern of anxiety-related attentional bias for threaten- ing words in subjects with high-and low-trait anxiety by repeating the occasions of stimulus exposures.Methods:High (upper 25%)and low(lower 25%)anxious individuals(N=24 and N=23 respectively)participated in a forced- choice reaction time version of a modified dot-probe task.There were 48 negative-neutral word pairs chosen as stimuli. Each word pairs were presented eight occasions in different blocks,and at each occasion the attentional bias to the e- motionally negative word was examined.Results:High anxious individuals showed initial selective attention to the neg- ative words when they were presented for the first occasion(t=2.34,P
3.Treatment of Hoffa fractures
Chinese Journal of Orthopaedic Trauma 2011;13(7):620-625
Objective To investigate clinical characteristics and treatment of Hoffa fractures.Methods Twenty patients with Hoffa fracture (24 condyles) were treated from January 2002 to April 2009.They were 14 men (18 condyles) and 6 women (6 condyles), aged from 20 to 70 years (average, 43. 3 years).There were 15 fractures of medial femoral condyle and 9 ones of lateral femoral condyle. Two rare cases were fractures of unilateral bi-condyles and one rare case fractures of unilateral bi-condyles plus contralateral single condyle. Four fractured condyles were old due to implant failure and 20 were fresh. According to the modified Letenneur's classification, there were 6 condyles of type Ⅰ, 4 condyles of type Ⅱ and 14 condyles of type Ⅲ.Fifteen condyles were fixed anteroposteriorly with 2 to 4 cancellous or canulated screws, 8 condyles were fixed posteroanteriorly with 2 to 4 screws, and one condyle was fixed with K wires. Five condyles were fixed with screws plus lateral supporting plates, and 3 condyles with screws plus posterior anti-sliding plates. Results All the patients were followed up for an average of 14. 4 months (6 to 84 months) . All the 24 condyles obtained bony union after an average of 18. 6 weeks (from 12 to 44 weeks). There was no infection, implant failure, nonunion or bone necrosis. According to Letenneur's functional assessment system, 16 condyles were excellent, 6 good and 2 poor, with a good-to-excellent rate of 91. 7%. Conclusions All Hoffa fractures should be treated with screws. Screw diameter, fixation direction and surgical incision should depend on facture type and size of fracture block. Unstable Hoffa fractures should be treated with screws combined with lateral supporting plates or posterior anti-sliding plates.

BACKGROUND:There are few clinical control ed trials about the clinical effects in patients with pertrochanteric femur fractures after treatment with short or long proximal femoral nail antirotation.
OBJECTIVE:To compare the clinical outcomes in patients with AO/ASIF-A1/2 pertrochanteric femur fractures after treatment with short or long proximal femoral nail antirotation.
METHODS:A total of 98 patients with AO/ASIF-A1/2 pertrochanteric femur fractures were treated by proximal femoral nail antirotation. They were divided into two groups according to the type of proximal femoral nail antirotation:short nail group (n=50) and long nail group (n=48). The operative time, blood loss, and hospital stay were recorded in both groups. In fol ow-up, fracture healing time, imaging and clinical complications were evaluated. In the final fol ow-up, Harris hip score was used to evaluate functional recovery.
RESULTS AND CONCLUSION:Compared with the short nail group, operative time was shorter and blood loss was less in the long nail group (P<0.05). No significant difference in hospital stay was detected between the short nail and long nail groups (P>0.05). Average fol ow-up periods were respectively (15.8±6.4) months and (16.2±5.7) months in the long nail and short nail groups.“Cutting-out”or infection occurred in five patients in the long nail group and three in the short nail group. Besides above-mentioned patients, the remaining patients in the two groups achieved fracture healing. No significant difference in average fracture healing time was detected between groups (P=0.588). In the final fol ow-up, no significant difference in Harris hip score was detectable in the two groups (P=0.204). The incidence rates of total postoperative complications in the long and short nail groups were 31.2%and 16.0%, respectively (P=0.075). Results suggested that no differences in the union and complication rates between the two groups were identified, suggesting that long nails offer no advantage compared with short nails for stabilizing AO/ASIF-A1/A2 pertrochanteric femur fractures.

Objective To study the efficacy, safety and related characteristics of ethylcellulose microcapsules containing tubeimoside as a vascular embolization agent. Methods The ethylcellulose microcapsules containing tubeimoside was prepared using tubeimoside from bolbostemma paniculatum of Chinese medicinal herb as the core, and ethylcellulose as the shell. Transcatheter renal arterial embolization was performed with the microcapsules in 30 New Zealand white rabbits. Results The microcapsules were white, spherical, and smooth particles, with its size to range from 40-180 μm, and its drug content was 36%(W/W); It was divergened best in 40% meglucamine diatrizoate and suspended stably, easily injected through 3 F catheter without occlusion. All of the microcapsules ruptured in about 20 days when immersed in physiological saline at 37℃. The embolized kidneys were smaller than the normal kidneys in weight and volume after 30 days(tw=102.1, tv=38.0, P<0.001). Serial slices of the kidneys showed that the microcapsules remained mainly at the interlobular artery and the arterial arch, which measured from 110 μm to 350 μm in diameter. The vessels maintained occlusive after 30 days without formation of collateral circulation. Conclusion Ethylcellulose microcapsules containing tubeimoside were safe and effective with angioembolic function and slow-release. It was a potential peripheral artery embolization agent.
